AUXILIARY CIIART COMPUTING MACHINE.

i application ined Maren 24, 192i.` serial No. 455,110.

To all whom t may concern: y Be it known that GREENE CARLTON HoscH, a citizen of the United States, residing in the city of St. Louis,v and State of Missouri,V

has invented new and useful Improvements in Auxiliary Chart Computingk Machines, of which the following is a specifica! tion.

This invention relates to measuringv and).v

l0V computing machines and the invention may be ap liedto any machine which performs or 1n icates a measurement and whlch mf cludes kmeans for indicating a computation which is a function ofthe indicated length. 'i

l5 In the present specification, the invention is described as embodied in a machine for iun dicating the length of anarticle such as a piece of fabric and which operates to com-` pute the sale charge to bemade for the 20 measured length at different prices or rates for the unit of measure.

' As usually constructed, these machines include a length indicator which indicates units of length and aliquot fractions of the unitV of length. Theyv also include a chart,

or charts which are driven in unison with the length indicatorand these charts bear` .computed figures which correspond to any length measured in units and the said aliquot fractions which are indicated by the scaleof the length indicator. They do not carry q any computations corresponding to smaller dlvislons than the aliquot fraction; for example, it is impossible to compute any quan- 36 tity not commensurable in eighths ofthe unit Y,

Theinvention consists in the novel fea` tures, and in the general combination of `parts to be particularly'dcscribed hereinafter,l all of which contribute to produce a simple and efiicientauxiliary chart comput-v A preferred embodiment of f ing.machine. v my invention will be particularly described in the following specification. while the,`

broad scope of my invention will-be out in the appended `claims.v y

In the drawlng. Figure 1 is a plan of a machine embod fing hay pointed chart as, partially extended as use;

auxiliary chart though y in i .-Figure 2 is ay vertical section taken through the machine about `on the line 242, of lFigurel and particularlyillustratin .the

Vrelation of the main chart or charts an the Figure 3 is a vertical sectionthrough the frame of the machine and particularly illustrating the driving train Aby means of which the main charts are driven from uring roller; and Q c Figure 4 is a side elevation showing` details of the drive to the length indicator.

Referring more particularly to the parts,

ll represents thecasing of the machine which .beof any suitable form and this casing 1s provided on its upper si de with a length indicatorcomprising a dial 2 which may be provided with two indicating pointersL or hands 3 and 4, the former of which' the dial; this scale alsoinclude's co-,operates with large f numbers 1y tol 12, ywhich form part of a scale on the face of fractional The pointer 4 `is driven so that it makes one complete revolution of the dialpas the pointer 3 is integersy on the face ofthe dial.

l Inaddit'on to this thel di l sca a plurality of smaller divisions 5 sions.

be usedwith any desired unit o moving through the space between adjacent le includes which are smallerthan the fractional spaces or divian f measure.

In the'present instance the unit of measure is supposed to be a yard and the fractional divisions represent eighths of a yard, while the divisions 5 indicate inches.

`The upper side of thecasingi prices or rates. In the present instance the y o5 s also constructed so as to display av chart'or charts ,are funct different casing is kprovided with two windows 6 and 7 and these windows are providedwith fixed scales `8 and 9, respectively, whichlcarry numbers indicating different prices per yard. Charts 10 are provided, see Figure 2, which are disposed beneath the windows, respectively, and ythese charts carry numbers 11 whichalign with the'numbers on the fixed scales 8 and 9. The numbers yon the ycharts are functions of the corresponding numbers on the fixed scale and also of the length indicated by the hands or pointers and 4. F or example. in Figure 1, the numbers on the charts indicate the .sale charges to be made for quantities increasing by eighths of a yard of material, at the differ'- ent rates.

It is not feasible to provide computations corresponding to inches on such a chart, although it is often desired to measure oif and sell a quantity commensurable only in inches. In order to overcome this diflicultyV Ya small bail or handle 16 which must be grasped to extend the chart when it is to be examined. The space on this auxiliary chart is divided into blocks or LSquares7 and each of the-se squares bears a price rate number, such as the numbers 32, 3G, 3S, etc. These numbers are the same price numbers or rates vvhich are carried by the scales 8 and 9 which co-operate with the main charts 10. In each square a small table is placed indicating the charge to be made at the rate for that square for different amounts, for example, an inch, 1 inch, etc. up to t inches; each square also carries a computed figure indicating the charge for of a yard and of a yard. In other words, these computed figures on thefauxiliary chart are interpolated With respect to the computed figures of the main charts.

In using a machine embodying my auxiliary chart any desired quantity can be measured and the computed charge readily ascertained. If the measured length is commensurable in eighths of a yard thcn the main charts Will indicate exactly the sale charge to be made. If the length is not eommensurable then it is merely necessary to add to the computed figure of the main chart, the additional amount to be charged for the number of inches to the nearest aliquot fraction for which the main charts carry computations.

Any suitable means may be provided for driving the indicating pointers 3 and 4 and the charts 10 in unison. A simple mechanism for this purpose is illustrated in Figures 5% and 1. The fabric to be measured is pulled between the measuring roller 17 and the presser roller 18, and the shaft of the measuring roller carries a pinion 19 (see Figure which drives a gear train including a large gear 20. A pinion 21 rigid with this gear wheel Q0 drives an idler which meshes with gear Wheels 23 carried on the shafts of take-up rollers 24 upon which the charts 1() wrap, (see Figmre These charts are normally held coiled upon a spring roller The drive to the pointers 3 and i is effected by means of a sleeve 2G (see Figure el) which is rigid with the large gear wheel Q0 and this sleeve carries a bevel gear Wheel 27 which meshes with another gear wheel 2S attached to the lower end of a spindle 29, the upper end of which carries the inch pointer 4f. On the tubular saindle) a reduction gear 3() is provided, the details of which are illustrated in the ap plication of John L. Wheeler, Serial No. 42,'1616, from which an outer tubular spindle 31 is driven, and this spindle at its upper end carries the pointer or hand It is understood that the embodiment of the invention described herein is only one of the many embodiments my invention may take, and I do not wish to be limited in the practice of my invention nor in my claims, to the articular eml'iodiment set forth.

That I claim is 1. In a measuring and cost computing machine having length indicating means and a chart driven in unison With the indicating means and bearing computed figures corresponding to a unit of measure and relatively large aliquot fractions thereof at different prices or rates for the unit of measure, an interpolating chart associated with the machine and constructed to be extended at the will of the operator, said interpolating chart bearing computed figures interpolated with respect to the computed figures of the first named chart and corresponding to relatively small divisions of the indicating scale at the same prices or rates per unit of measure.
